Royal Purple - High Performance Motor Oil - Synthetic

Royal Purple® Motor Oil is recommended for use in all four-cycle gasoline engines and both two-cycle and four-cycle diesel applications including cars, trucks, motor homes / RVs, boats, commercial fleet and stationary industrial diesel engines.

Royal Purple® Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec® additive technology.

Synerlec® additive technology greatly reduces engine wear, including ring, cylinder and bearing wear. It is extremely tenacious, adheres to engine surfaces and remains after shutdown, which provides protection upon initial startup.

Royal Purple gains its performance advantages from its proprietary additive technologies such as Synerlec®.

Synthetic oils enable Royal Purple to make superior lubricants, but it is Royal Purple’s advanced synthetic additive technologies that gives Royal Purple’s lubricants their amazing performance advantages. Royal Purple’s proprietary additive technologies such as Synerlec® truly are beyond synthetic.™

Royal Purple’s advanced synthetic additive technologies such as Synerlec® form a tough, slippery, synthetic film on all metal surfaces. This proprietary film significantly improves lubrication: first, by increasing oil film thickness and second, by increasing oil film toughness, both of which help to prevent metal-to-metal contact. It displaces moisture from metal surfaces and protects all metals against rust and corrosion. It also fortifies the oil against the detrimental effects of heat, which causes oil to oxidize.



Royal Purple® Performance Advantages:

• Greater Wear Protection: Synerlec® additive technology forms a tough, tenacious film on all metal surfaces virtually eliminating engine wear.

• Greatly Extends Oil Drain Intervals: Royal Purple® Motor Oil is extremely oxidation stable and stands up to the heat that causes oils to thicken, to form lacquer and varnish deposits, to lose its lubricity and to shorten the life of both the oil and the engine.

• Superior Corrosion Protection: Synerlec® additive technology protects during normal and severe operation and acts as a preservative oil during shutdown.

• Saves Fuel: Royal Purple® Motor Oil's low coefficient of friction routinely produces meaningful improvements in fuel economy.

• Reduces Exhaust Emissions: Royal Purple® Motor Oil provides a superior seal between the piston ring and cylinder wall, which reduces blow-by, improves combustion efficiency and measurably reduces harmful emissions.

• Increases Horsepower: Royal Purple® Motor Oil increases horsepower and torque over conventional oils.

• Keeps Engines Clean: Royal Purple® Motor Oil's natural solvency cleans deposits left by previous oils and keeps engines clean.

• Mates Engine Parts: Synerlec® additive technology allows engine parts to perfectly mate. Mated parts allow engines to run smoother with increased efficiency for maximum performance.

• API Warranty Approved: Royal Purple's SAE grade motor oils are API licensed and will not void new car warranties. They are compatible with other mineral and synthetic motor oils.

• Will Not Harm Seals: Royal Purple® Motor Oil has the same excellent seal compatibility as mineral engine oils.

• Environmentally Responsible: Royal Purple® Motor Oil components are TSCA listed and meet EPA, RCRA and OSHA requirements. Royal Purple® Motor Oil extends oil drain intervals, eliminates premature oil changes, decreases the amount of oil purchased and disposed of and conserves energy.
